This will utilize an architecture involving multiple peers and a single local Icecast server, all communicating over the local wireless network/mesh. When a user intends to broadcast a new video, the client will automatically send a request, authentication and identification details, to the classroom's Icecast server. The Icecast server does not necessarily have to be a dedicated server; the software could, for example, be running on the teacher's laptop; it would merely need to advertise its service via mDNS. Once confirmed, the stream is then uploaded and streamed to the local Icecast server via GStreamer, creating a unique URL for the stream. When the user invites others, or perhaps the entire class, to view the stream, then it would send the URL of the stream to the target user, and the peer's identification details. This would be done through the central server to increase security by making spoofing more difficult. By utilizing an external Icecast server to handle the video broadcasting itself, even a resource-constrained machine such as an XO-1 should be able to broadcast video, albeit encoded with less cpu-intensive codecs and settings to compensate for the lack of cpu power on such machines.

Since Icecast lacks support for multicast broadcasting, another FOSS streaming server such as Helix Server or VLC may need to be used; I will investigate this prior to the start of GSoC.
